The embodiment of the invention discloses a TD (time division) frequency planning and scrambling code
planning method based on an adjacent zone priority level, comprising: an adjacent
cell priority level is generated through a zone adjacent factor, a zone factor and a zone direction factor based on the
base station zone attribute according to the
system technical scheme; and a TD main carrier frequency is distributed according to the generated adjacent zone priority level to ensure the minimality of the frequency interferences among zones; and then, a
system assigns base scrambling code blocks and scrambling codes according to the adjacent zone priority level and the frequency so as to ensure the average minimization of the mutual interference of the frequency scrambling code among zones. According to the embodiment of the invention, the calculation method of the adjacent zone priority level is more reasonable, and the setting and switching process of the adjacent zone relationship is more reasonable. Furthermore, co-frequency encounter phenomena among the adjacent zones are avoided by adopting the scheme, so that the
mutual correlation of the scrambling codes among the adjacent zones is minimal, and the maximal frequency resource and scrambling code
resource utilization and the minimum frequency and scrambling code interferences among zones are ensured. And the
network performance indexes such as call completing rate are improved, and the
client perception quality is greatly improved.
